Total nucleic acids are extracted from a culture of cells and are then mixed with resin beads to which the polynucleotide 5'-TTT

TTTTTTTTTTTTTTTTTT-3' has been covalently attached. After a short incubation, the beads are then extracted from the mixture. When you analyze the cellular nucleic acids that have stuck to the beads, which of the following molecules do you expect to be most abundant?A. DNA.
B. tRNA.
C. rRNA. (it is not this one, I put this and it was wrong.)
D. mRNA.
E. Primary transcript RNA.

Answer:

D. mRNA.

Explanation:

Polyadenylation is defined as the addition of poly (A) to messenger RNA. This tail is made up of several adenosine monophosphates (adenine bases). In eukaryotes, polyadenylation is part of the process in which messenger RNA is formed for subsequent translation. Therefore, it is part of the process of gene expression.

Answer: D mRNA

Explanation:

mRNA (Messenger RNA) is a single-stranded RNA molecule that corresponds to the genetic sequence of a gene and is read by the ribosome in the process of producing a protein and it carries the genetic information copied from DNA in the form of a series of three-base code “words,” each of which specifies a particular amino acid.mRNA is the most abundant because it is the only type of RNA that is polyadenylated and the poly (A) tail would be able to base pair with the strands of poly(T) on the beads and thus stick to them. DNA would not be found in the sample, as the poly (A) tail is not encoded int he DNA and long runs of T are rare in DNA.

What is over utilisation
bixtya [17]
Over utilisation of resources is the unlimited and careless use of any resource or utility. It refers to the excessive use of something to a point that in return we are deteriorating the resource. It can also be termed as exploitation or sustainable use. In the 21st century, we must focus on sustainable development and not over-utilisation of resources.

How much of the organisms that lived on Earth do scientists believe are represented by the fossil record?
Nimfa-mama [501]

Answer:

2%

Explanation:

The scientist believe that around 2% of the species that existed on Earth have been preserved in the fossil records. It is still a hot debate about it though, as there are only around 250,000 species identified in the fossil records so far, which is less than a quarter from the species that live in the present.

The reason why scientists believe that the majority of the species have not been preserved are very logical though. One of the reasons is that lot of species existed very long time ago, so their remains just didn't lasted so long. Other reason is the movement of the plates, where we have situation where plates that existed in the past have been totally suducted and melted in the mantle, while others are at the verge of it, so every fossil with them is melted and destroyed too. Another reason is that lot of species do not have hard parts, solid bone structure, so their preservation has been pretty much impossible,

In pea plants, round peas are dominant (r) and shriveled peas are recessive (r), and yellow peas (shown as light gray in the pun
Debora [2.8K]

The right answer is 3:3:1:1


A Mendelian inheritance (classical or monogenic) is a transmission of a single gene in a dominant, recessive or linked to X (this is the case in this question, offsprings are made by crossing the genotypes between the two species).

Discoveries on the structure of DNA, the genetic code, the genome and the observation of genetic traits and diseases that do not comply with the laws of formal genetics (Mendelian inheritance) have led researchers to define other modes of transmission including those related to multifactorial and mitochondrial inheritance (non-Mendelian inheritance).

gregori [183]

A client consumed approximately 40 g of protein in the past 24 hours. his 24-hour urine collection indicated a urine urea nitrogen of 12 g. his nitrogen balance would be calculated as option(e)i.e, -9.6 g.

A clear urine signal indicates adequate hydration and maybe overhydration. A healthy level of hydration is indicated by pale yellow urine. More fluids should be consumed if your urine is dark yellow. Urine with an amber hue may be a sign of dehydration. Orange urine is a common side effect of many meals and drugs as well as a potential indicator of liver issues.

It is possible to fertilize with urine. It serves as a territorial marking for some animals. In the past, aged or fermented urine (also known as lant) was used to make gunpowder, clean homes, tan leather, and color fabrics.

Equation: N2 balance = (dietary protein intake/6.25) - (urine urea nitrogen +4)

N2 balance = ( 40/ 6.25) - ( 12 + 4)

N2 balance = - 9.6g

The complete question is:

A client consumed approximately 40 g of protein in the past 24 hours. His 24-hour urine collection indicated a urine urea nitrogen of 12 g. His nitrogen balance would be:

Equation: N2 balance = (dietary protein intake/6.25) - (urine urea nitrogen +4)

a.) -12.1 g

b.) -4.2 g

c.) 9.6 g

d.) 4.2 g

e.) -9.6 g
